It was quite useful until all the humanizing models came. Now, it highlights more than half the text as AI and tells you 2% AI. I don't get it. Also, there is no one to reach out to for customer se... See more

This tool is a total scam
This tool is a total scam, it gives too many false positives flagging an entire paragraph as “AI generated” just for using 1 or 2 technical or formal words that are very common in essays, application/motivation letters.
I absolutely would not recommend it for reviewing any formal document, paper or essay… It’s basically snake oil
it very good
Accurate AI detector
only correct AI detector. not 100% accurate, but the best option

It gave me some really interesting feedback and also told me what A.I.-sounding sentences I should change. Super helpful in my 7-page research essay on computer processing chips. Highly recommend!
Great tool for teachers
GPTZERO helped me finish correcting my students' assignments within minutes after being used to spending hours to complete the task. It also facilitated the process of giving feedback on their writing. It is a very useful tool

There are too many ads to sort out/to go through before I can start uploading the test material to be investigated. Three times, I had to leave the page to refresh.
A wonderful experience
It's been a wonderful experience using GPTzero to check for AI assistance. I have become so cool with using it always.

Bookmark it! Super helpful!
This is a great tool for me to quickly scan text to determine the likelihood that it is AI generated. It is easy to use and the interface is very user-friendly.
Great Tool for Detecting AI-Generated Text
ChatGPTZero has been really useful for checking if something was written by AI. It’s quick, easy to use, and gives a clear breakdown of its results. I’ve tested it on different types of writing, and it does a solid job of flagging AI-generated content.
The confidence scores are helpful, and I appreciate that it doesn’t just say “AI” or “human” but actually explains why. Definitely a useful tool for educators, writers, or anyone who wants to verify content authenticity.
It’s a great tool
It’s a great tool, to see how my essay looked before turning into uni, I used chat gpt for some and it helped me see where I needed to change

The Perfect Tool for Students and Instructors
GPTZero is an AI detection tool designed to identify text generated by large language models like ChatGPT. Marketed primarily for educators, content creators, and professionals, it aims to distinguish between human-written and AI-generated content.
Pros
✅ User-Friendly Interface – The platform is straightforward and easy to navigate, making it accessible even for non-technical users.
✅ Speed & Efficiency – GPTZero quickly scans and analyzes text, providing near-instant results.
✅ Detailed Analysis – It offers breakdowns of text "perplexity" and "burstiness," two key factors in AI detection.
✅ Useful for Educators – Many teachers and institutions use it to verify student submissions and detect AI-assisted writing.
Cons
❌ False Positives & Negatives – No AI detector is 100% accurate, and GPTZero sometimes misidentifies human-written text as AI-generated (and vice versa).
❌ Limited Free Version – While there’s a free option, advanced features require a paid subscription.
❌ Struggles with Hybrid Texts – If a piece is partially written by a human and partially by AI, the detection can be inconsistent.
